Application filed July 9,

In reroofing buildings with prepared roofing material usually made out'ot heavy paper saturated with tar or asphalt and laid on in long strips overlapped at their meeting edges and nailed, there are generally unsupported portions between the sheeting-boards, where the previous covering of wooden shingles have been removed, and between the butt ends of the shingles in each course in where the prepared roofing is laid directly upon the old root without removing the wooden shingles. Such unsupported places cause the sheets of prepared roofing to be broken through in time by hail, by persons :5 walking over the roof and the like, which v causes leakage.

The object of this invention is to support and cushion the covering of prepared roofing that this breakage will be avoided.

A further object is to provide an inexpensive supporting and cushioning material that will be strong, light in weight in order not to materially add to the roof load, and which will be profuse with dead air spaces that fur- 2 ni'sh such insulation as reduces the fire hazardfand equalizes the temperature under the roo v v I accomplish all of the above and other less important objects which will hereinafter appear, by the means illustrated in the'ac- 'companying drawing, in which- Fig. 1, is a perspectiveyiew of a roof, -showing rafter and sheeting, but no wood shingles, and showing acovering of prepared roofing supported byn'iy invention at the spaces between the sheeting boards;

Fig. 2, is .a roof-detail in vertical section, showing a cover of ready roofing laid over wooden shingles, with a two ply or double layer otmy strengthening and cushioning material in between;

Fig. 3, is a perspective view on a larger scale of the two ply ordouble layer of intervening material such as used in Fig. 2. This view shows the corrugations of the two layers running at right angles to each other;

Fig. 4, is a perspective view of a modified one-ply material in which the asphalt felt for theoutside of the roof is made integral with the corrugated cushion. 4 Like characters of reference indicate like parts in the several views of the drawing.

i In the drawing, the rafter 5' and sheeting boards-6, and prepared roofing material 7 1926. Serial No. 121,457.

are of usual material, assembled in the usual manner.

My invention consists incombining a builtup layer 8 by interposing it between the prepared roofiim' 7 and sheeting boards 6 as shown in Fig. 1. The material. 8 is comprised of two sheets 9. and 10, of strawboard, between which is. adhesively assembled a corrugated sheet of straw-board 11. The assembly is retained by driving roofing nails 12 through the'l'ayers 7 and 8, into sheetingboards 6. y c

The corrugations in sheet 11 of material 8. form air spaces between sheets 9 and 10, that act. as nonconductors of heat, and the curves of the corrugations make sheet ll'.

yield under sufiicient impact or pressure, while the strawboard. being appreciably elastic, gives it a desired resiliency which restores the thickness of the material-as a whole after the pressure is removed.

.In'the embodiment shown in Fig. 2, the reroofing is done without removing the old wooden shingles 13. The prepared roofing material 7 is the same as shown in Fig. 1, and the built-up material 8' differs in that it is two ply or of double thickness in which the corrugations 14 and 15 of the two corrugated sheets preferably run in directions which are at right angles to eachother, which increases the initial resistance and the resiliencyof the filling, as a whole. This is best shownin Fig. 3.

Figure, t illustrates a specially prepared material wherein a sheet of prepared roofing 17 is substituted for one of the sheets between which the corrugated sheet of strawboard is glued. In making laps with this the bottom sheet and corrugated sheet are cut away with a knife leaving the top layer .to lap over the next roofing layer below.

Having thus fully described my invention. what I claim as new and wish to secure by Letters Patent, is-

1. In a roof, an outer water-proofed layer of prepared roofing, a support to which it is nailed having depressions horizontally across the roof forming shoulders with sharp corners and a cushion between the first two com: prising corrugatedstraw-board having air spaces in the corrugations.

2. In a roof, an outer water-proofed layer of paper material, a support to which it is nailed having depressions horizontally across the roof forming shoulders with sharp corners, and a cushion between the support and outer layer comprising one or more straight sheets of straw-board separated by one or more corrugated straw-board sheets, said corrugations forming air spaces between the straight sheets of the cushion.

3. In a roof, an outer water-proofed layer of paper material, a support to which it is nailed having depressions horizontally across the roof forming shoulders with sharp corners, and a. cushion between the support and outer layer comprising a plurality of strawboard sheets adhesively united with a plurality of corrugated sheets the'corrugation of each sheet running in opposite directions to those of the next corrugated sheet, said corrugations forming air spaces between the straight sheets of the cushion.

In testimony whereof I aflix m si nature.
